NullableRotationalFrequency

Overview

Abstract data type

A physical quantity of dimension T^-1 (inherited from NullableFrequency) for the application type rotational frequency. NullableRotationalFrequency is abstract and has two concrete subtypes:

• a RotationalFrequency is an actual value for a physical quantity with a numerical value and a unit of measurement;

• a NullRotationalFrequency is a null value that explicitly indicates the absence of an actual physical quantity.

Supertypes

• NullableFrequency

Subtypes

• NullRotationalFrequency

• RotationalFrequency

Implementation in Proteus Schema

All data attributes with type NullableRotationalFrequency are implemented as DEXPI generic attributes for physical quantities.

Example

See the examples for RotationalFrequency and NullRotationalFrequency.
